DESCRIPTION
The  ZMY20  is  an  extremely  sensitive  magnetic  sensor  employing  the
magneto-resistive effect of thin film permalloy. It allows the measurement of
magnetic fields or the detection of magnetic parts. The highly sensitive and
small size magnetoresistive sensors consist of a chip covered with thin film
permalloy stripes. These stripes form a Wheatstone bridge, whose output
voltage is proportional to the magnetic field component Hy. A perpendicular
field Hx is necessary to stabilize sensor operation. This can be done by using a
small permanent magnet.
FEATURES
" Output voltage proportional to magnetic field Hy
"  Adjustment of sensitivity and suppression of
hysteresis by the auxiliary magnetic field Hx
"  Magnetic fields vertical to the chip level are not
effective
APPLICATIONS
"  Linear position sensors for process control, door
interlocks, proximity detectors, machine tool
sensing
"  Scalar measurement for compassing
"  Automotive  door switches, engine position &
speed sensing
"  Metering of fluids by sensing rotation of impeller
"  Traffic counting & vehicle-type sensing
"  Measurement of current in a conductor without
connection
